State-dependent, or parametric, noise is an essential component of the neural control mechanism for stick balancing at the fingertip. High-speed motion analysis in three dimensions demonstrates that the controlling movements made by the fingertip during stick balancing can be described by a Lèvy flight. The Lèvy index, alpha, is approximately 0.9; a value close to optimal for a random search. W...

Objectives: The objective of this study was to explore and describe the experiences of University of Namibia nursing students on needle stick injuries. Methods: A qualitative exploratory was used. Unstructured individual interview was conducted to collect data from ten nursing students who were purposively selected. Thereafter, data were analyzed using content thematic qualitative analysis. The...

From the Book of Job, Chapter 38:1, 33–37: 1 Then the LORD answered Job out of the storm. He said: 33Do you know the laws of the heavens? Can you set up God’s dominion over the earth? 34Can you raise your voice to the clouds and cover yourself with a flood of water? 35Do you send the lightning bolts on their way? Do they report to you, “Here we are?” 36Who endowed the heart with wisdom or gave ...

Abstract—The aim of this study was to determine the effect of oils on chemical, physical, and sensory properties of deep-fried dough stick. Five kinds of vegetable oil which were used for addition and frying consist of: palm oil, soybean oil, sunflower oil, rice bran oil, and canola oil. The results of this study showed that using different kinds of oil made significant difference in the qualit...

Comprehension of stick-slip motion is very important for understanding tribological principles. The transition from creep-dominated to inertia-dominated stick-slip as the increase of sliding velocity has been described by researchers. However, the associated micro-contact behavior during this transition has not been fully disclosed yet. In this study, we investigated the stick-slip behaviors of...

Three experiments examined the role of reference directions in spatial updating. Participants briefly viewed an array of five objects. A non-egocentric reference direction was primed by placing a stick under two objects in the array at the time of learning. After a short interval, participants detected which object had been moved at a novel view that was caused by table rotation or by their own...

In a Monte Carlo study the conductivity of two-dimensional random stick systems is investigated from the percolation threshold up to ten times the percolation threshold density. We propose a model explicitly depending on the stick density and junction-to-stick conductance ratio. The model describes the transition from the conductivity determined by the structure of a percolating cluster to the ...
